18.1 Pre-emptive Priority Call (PPC)
There are five editable options in this menu.
A Pre-emptive Call is not a call that enables a user to go to the top of a queue. If two people, A & B,
are in a call and a user C, with pre-emption wishes to talk to B, then the call set up for user C will
interrupt (drop) the A/B call to set the call up with B.
User A has been pre-empted.
18.1.1 Originating PPC Private Call
Selecting this check box allows PPC Private Calls to be made using this terminal.
18.1.2 Call Priority for Outgoing Private PPC PTPC
This option is used to define the PPC priority used when initiating a PPC PTPC.
PPC - Pre-emptive Priority Call.
PTPC - Point to Point Call.
The range is 12-15. Priority 15 is also the emergency call priority, but pre-emption will not interrupt
an emergency call.
Note:
• If the call priority of the incoming PPC call is set to 12 or 13, the terminal will either allow the
call or reject it without any intervention by the user.
• If the call priority of the incoming PPC call is 14 or 15, the active non-emergency call will be
pre-empted.
• In Data mode, the terminal will only accept a PPC call with Emergency priority 15.
